lb a/ZZ La7/1.0712, t may concern:

Be it known that I, ADAM STEINKOENIG, a citizen of the United States of Americaand a resident of Cincinnati, county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Filters, of which the following is a specification.

The object of my invention is a filter of the class that utilizes pulp or similar material as a filtering medium, in which the liquid after having passed through the medium collects quickly and passes freely from the filtering chamber into the reservoir, and inwhich the' entrance of the liquid into the filter is regulated so as not to displace the filtering medium. This object is attained bythe means described in the specification and illustrated in the accompanying drawings, in which- Figure l is a plan viewof the main vessel of the filter embodying my invention, the fltering medium, the plate for supporting the same, and thecover of,v the filter being removed. Fig. 2 is a central longitudinal seotional view ofthe filter embodying my invention complete. Fig..3 is a perspective View of one-half of the plate which supports the filtering medillm.

Referring to the parts, the main vessel A consists of a shallow circular dish having a central hub a of a height slightly less than the height ot' the vertical wall of the vessel. Leading into hub a is a channel 0,', which is upon the bottom of vessel A and extends to the outside of the vessel, where it has a boss interiorly screw-threaded to receive pipe F, through which the murky liquid is admitted under pressure to the vessel. Vessel A has an interior collar a2, upon which rests supporting-plate B, upon which the filtering medium C is placed. Plate B has a series of concentric grooves b. Each of grooves l) has in its bottom a series of perforations b', passing through plate B. The pulp O is kept from being displaced by the inflowing liquid by means of a perforated plug G, which is screw-threaded to fit the interior of hub a and is placed Within the hub at a distance below ed to engage interior screw-threads upon the upper edge of the vessel.

In operation the liquid to be filtered-as,

for instance, whisky-is admitted through pipe F under pressure and passes in through channel a up through hub a. The plug G allows the liquid to flow in 'only at acertain rate, so that it does not wash the pulp out of place. After passing through plug G the liq- .uid passes in upon top of the filtering medium, the ring G' preventing it from washing `the pulp from around the hub. While plug G regulates the rapidity of the in flowing liquid, it does not diminish the pressure upon the liquid in vesselA. The pressure causes the liquid to be forced down through the pulp C. The grooves b collect the liquid after it has passed through the filtering n1e dium, and from the grooves b it passes quickly through perfor-ations b' into the reservoir in the bottom of Vessel A, from whence it may be drawn by means of a faucet E.

What I claim isl. In a filter, the combination of a main vessel, having an inlet-pipe extending up from its bottom, a perforated plate dividing the vessel into a filteringchamber and a reservoir, a filtering medium of the character described upon the plate, a perforated plug in the inlet-pipe for regulating the rate of influx substantially as shown and described.

2. In a filter, the combination ofa main vessel having a central hollow4 hub, a perforated plate dividing the vessel into a ltering-chamloer and a reservoir, a filtering medium upon the plate, a perforated plug within the'hub and a ring surrounding the hub and resting upon the filtering medium substantially as shown and described.
